Answer:
25
Step-by-step explanation:
130+25+25=180
..........
.....
The magnitude of the vector is √(7^2+12^2)=√(49+144)=√193
The direction is α=arctan(y/x)=arctan(12/-7)≈-59.74 however this is relative to the negative x-axis so we add 180° to get the standard angle...180-59.74=120.26°
So the vector is √193 @ 120.26°
Answer:
0.33

V = a²h/3
Plugging values in we get 8.67X10^7, or 86,700,000
